Abstract
La presente invencion se refiere a un método para complementar una imagen digital con elementos de imagen, mediante el cual se puede generar señales de prediccion que tengan pequeños errores, para una imagen digital en la cual los objetos se mueven grandemente a través de un proceso que no causa un largo tiempo de retardo y que no necesita de una gran cantidad de cálculos. En el método la imagen se divide en dos áreas. Los valores muestreados no significativos de las áreas que contienen la frontera o límites de la forma de un objeto, se transforman con unaf uncion de los valores del elemento de imagen significativos cerca a los valores del elemento de imagen no significativo, y se usan para complementar la imagen digital. También se describen un condificador de imágenes digitales y un descodificador de imágenes digitales, mismos que utilizan el método.
